Hi guys,

Maybe someone can help me with a little issue that I have.

I have a server on OVH and in same server I have about 20 websites that uses same IP.

Now I want to launch a new website but with a different IP, so I buy with OVH an IP FailOver to use in that website.
Everything is working great, the new website already have the new IP.

But after I use some sites to see if my new IP is blacklisted anywhere, I found the same error in many sitesl, saying:

IP.v4BL.org v4BL.org (D. D. N. S. B. L.)

94-23-78-68.ovh.net looks like dynamic IP address or PTR record looks like generic.

D.D.N.S.B.L (v4bl.org)

Etc...

I have contacted platinumservermanagement.com that made the management of my server and they said:

D.D.N.S.B.L is the ISP filters to avoid spamming on the server. Currently your IP address 94.23.78.68 do not have any reverse DNS i.e. rDNS set that is the reason it is blocked.
I recommend you to set the rDNS for the IP address 94.23.78.68 to point to thebestpaysites.com. You can contact your server provider to set this for you.
Once it is set you can contact D.D.N.S.B.L and request them to remove your IP address from their blacklist.

I have contacted OVH and Im still waiting for an answer.

Meanwhile I have contacted the namecheap.com where the domain is, but they also said that must be with the host provider too.

I also find a strange thing, in my domain name server setup, I have this:

Currently is using "Use Namecheap Hosting DNS Servers" option. I think that is not good. But my website is working fine..

I was checking the options inside the OVH account panel and find this:

Should I change anything here?

Also find this tutorial:

I know that the message is a little confuse, but can someone please help me fixing this issue?

Thanks,
Tim

Many mail servers require the IP to have a matching RDNS PTR record or they will not except mail form you. You can set the RDNS name in the control panel "reverse"

In the case where you have many sites using the same IP... like on a cPanel server... the server will send mail out on the root IP and this is common to all sites hosted on the same server. Make sure you have the hostname of the server setup as a "A Record" on the root IP and make sure you have a matching RDNS record.
 
You can easily set the rDNS using the OVH Panel

Make sure the rDNS is same as the hostname and a proper A record points to it.
 
Thank you for your replies guys.

ServerPolice, are you meaning this?

I cant use the hostname in both fields.
But I entered my domain.com in there and it seems to work.
Now I think that I need to wait 24 hours for propagation, right?

Yes, and you cant have hostname on both, just keep the hostname on primary and you will be fine.
Be sure to point the A record to server IP.

And it takes ~24-48 hours for the change to appear.
